Letters Patent No. 83,428, dated October 27, 1868.

IMPROVE!) APPARATUS FOR TOLLING- GRAIN.

The Schedulereferred to in these Letters Patent'and making part of the same.

Beit known that we, WILLIAM S. WIDGER and WILLIAM M. READ, of Fairiield, in the. county ofl The object of this Vinvention is to providea simple`v and reliable Alneansfor automatically tolling gra-in in grist-nills. v

It consists of a rotary funnel, provided lwith a spout that may be adjusted to the same fractional portion Yoi' the surface ofthe mouth ofthe funnel as the factional part of the grain to be taken. Thisfunnel is soar ranged that the grain must pass vthrough it while it is in rotary motion. The area 'of thespout is proportional to the entire area of the mouth of the funnel. For instance, the area of the spout maybe to that of 'the mouth of the funnel, as Ito 6. At each revolution of ,the funnel, the spout receives and conveys away a certain proportion of the entire amount oi' grain falling into the funnel. This proportion may be varied by adjusting the spout. Thus, if, as before stated, the area of the spout, when fully extended, be to the area of the mouth of the funnel, as 1 to 6,tl1en the area of thc spout when half open will he to the area ofthe mouth oi' the funnel, as l. to l2. The proportion may be varied to a greater or less degree, as may be desired, as will he more fully described on reference to the accompanying drawings, wl ierein- A represent-s a funnel provided with a shaft, B, which is rigidly secured to it, and arranged so as to suspend the funnel under a spout, in a position to'bc rotated by a belt working over a pulley on the said shaft.

C represents a spout, the. inner end of which is fixed to the` shaft, and the outer end to the side of the funnel, ina recess therein. The said spout is made of two parts, one of which, C', is arranged to oscillate on the shaft B, and is provided with a curved arm,

at its outer end with a boss, (L, anda lip, b, the latter being bent over the edge of the funnel, serving as a guide for the arin D. A set-screw Ais fitted into the boss a, passing through ajslot in the side of the funnel, whereby the spout C may be adjusted to and secured at any desired fractional portion of the area of the mouth of the -iiuinelvithin the united capacity' of the two parts "of the spout.

E represents a iixed spout on the outside of the funnel, communicating with the mouth ofthe spout C.

In Vusing our improved apparatus, we arrange it under a spout through which the grist to be tolled is to pass, so that the grain must also pass through the funnel, and set it into rotary motion, whereby the spout AG will, at cach revolution, receive a portion of the passing grahnand convey it out of the spout or channel through which the grist flows. The amount so received Vby 'the spout C will be a certain proportion of the entire amount oi' grain falling into the funnel, according to the 'relative areas of the spout and the funnel. The spout maybe adjusted tothe fractional` part'of the funneleorrespomlingto the vpa-It to be taken from the grain, and the funnel may he provided with a scale to which the. lip b may also serve as a pointer to indicate the proper position for setting the spout for the difierent parts to be taken.

Instead of a funnel-shaped vessel, a cylindrical tube may be used, but we prefer, for convenience, to make them inthe forni of a funnel.

Having thus described our invention,

'e claim as new, and desire to secure by Letters Patent-- .lhe rotary funnel A, having a spout provided with the movable part G', adjusted by means rof the slot and set-screw, all arranged and operating substantially as herein set forth.
